3.5.4. Alarm Module (Option AM2)
The module offers two freely configurable relay outputs for alarm or control purposes. Various operation modes
are available including switch hysteresis, switch window and error indication. The error modes can be configured
independently from each other. The measurands at the outputs as well as switching points, hysteresis and the
normal.state.(standard./.inverted).can.be.set.via.PCS10.Product.Configuration.Software.or.using.the.push-
buttons (see chapter 11.3 Optional Menus, Fig. 55 Alarm output).
Switch Hysteresis Mode
The switching behavior is determined by entering a switching point and an associated hysteresis value.
